XADM: Free Disk Space Requirements for Eseutil.exe

This article was previously published under Q183888
This article discusses the amount of free disk space required to run theEseutil.exe program that ships with Microsoft Exchange Server version 5.5.
Eseutil.exe can be used to defragment, repair, or check the integrity of aMicrosoft Exchange Server database.

The amount of free disk space needed to defragment a database (Eseutil /d)is 110 percent of the size of the file being defragmented.

When you repair a database (Eseutil /p), the amount of free disk spacerequired depends on the number of corrupt pages in the database. This isdifferent from how the older Edbutil.exe program repaired databases.Normally, 25 percent of the file being repaired is a conservative estimateof the amount of free disk space required.

Checking database integrity (Eseutil /g) is an in-place operation and doesnot require any additional free disk space.

In the case of the defrag or repair operations, the /t command line switchshould be used to specify the location of a temporary file. This fileshould be located on a drive that has the required free disk space. Thiscan be a local or a network drive.
